Power Conditioning Help Please?

Good question re: budget. I try to make a habit of buying "near state of the art" gear...and always second hand to attain excellent bang for the buck. Deciding on budget for "tweak" gear like power conditioning seems a bit dicey for me. If I KNEW I'd hear considerable, positive impact, I'd be willing to lay down for something good...make sense?

Thanks to all for the advice and counsel...the ball is in my court now and I appreciate your collective feedback.

Thank you for responding. No...no dedicated circuits or high-end outlets. Not sure if dedicating the circuits is practical due to limited outlets...required for non-audio devices. Have seen ads for outlets, but didn't understand if they'd make a difference or not.

Presently, I have most of my stuff plugged into a cheap Monster Cable conditioner.

Your response brings about a question. How does one know if his power is clean or otherwise?
